是⼀个守护进程，利⽤它可实现 cluster-level logging 。 04-K8s组件 17 Kubernetes API API conventions doc 中描述了API的总体规范。 API Reference 中描述了API端点、资源类型和样本。 access doc 讨论了API的远程访问。 Kubernetes API也是系统声明式配置模式的基础。 Kubectl 命令⾏⼯具可⽤于创建、更新、删除以及获取API对象。 apiVersion: $GROUP_NAME/$VERSION （例如 apiVersion: batch/v1 ）。 ⽀持的API组的完整列表可详⻅：Kubernetes API reference 。 使⽤ custom resources 扩展API有两个⽀持的路径： 1. CustomResourceDefinition 适⽤于⾮常基本的CRUD需求的⽤户。 2. 即将推出：⽤户需要完整的Kubernetes name 字符串，UID和可选的 namespace 您还需要提供 spec 字段。对于不同的Kubernetes对象来说， spec 的格式都是不同的。 Kubernetes API reference 可 帮助您找到所有对象的spec格式。 原⽂ https://kubernetes.io/docs/concepts/overview/working-with-objects/kubernetes-objects/
